Insufficient use of installed memory

[Thorsten Breitfeld]

I have a small problem, that maybe someone can help me with:

I am working on a Sparcstation 1  (SUN 4/60) under SUN-OS 4.1 with
40 MBytes of memory installed. Swapspace is configured to 50 MB.

When executing a large FORTRAN program with a Blank Common of
20 MB, the program seems to get no more then about 10 percent
of memory (see below). I am the only user on the computer,
but the performance is really bad.

USER  PID %CPU %MEM    SZ  RSS TT STAT START  TIME COMMAND
xxxx 7712 38.3  6.6 22624 2596 p1 R    10:45  21:15 ./freq2.out
xxxx 7911  8.3  0.7   168  264 p2 R    12:26   0:00 ps -u
xxxx 7593  0.4  0.5   240  188 p2 S    10:03   1:07 cmdtool

xxxx 7703  0.0  0.0    80    0 p1 IW   10:44   0:00 /bin/csh permas freq2 -e
xxxx 7576  0.0  0.0   136    0 p0 IW   10:02   0:00 cmdtool -Wp 0 0 -WP 0 0 
xxxx 7594  0.0  0.0    80    0 p2 S    10:03   0:01 -bin/csh (csh)
xxxx 7583  0.0  0.0    92    0 p1 IW   10:02   0:01 -bin/csh (csh)
xxxx 7577  0.0  0.0    80    0 p0 IW   10:02   0:00 -bin/csh (csh)

For explanation: PID 7703 executes 7707 which runs 7712.

What can I do to use more of the 40 MB memory for my program ?

Thanks alot,
Rainer
